A new study finds GM genes are still entering native Mexican maize varieties despite a ban on GM maize cultivation in Mexico. The research, led by Dr Sarah Agapito-Tenfen, examines community seed management and social organization in Oaxaca as factors determining contamination.
Contamination concerns can affect market access and segregation premiums for non-GM maize, which matters for buyers sourcing corn from Mexico. The direct price impact is limited, as this is a research and regulatory story rather than a supply shock.
After 770 past neutral report events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.1% to +1.6%), and +0.7% over 20.
